Wooden bed frame for supporting a mattress

ABSTRACT

The Drawer-sommier is another way of making a bed with regard to the former technique, using wood without making use of iron to achieve the traditional small-board grill ( 2 ) sommier firmness, and ussing wooden crossbars ( 3 ) sufficiently high to hold the weight of the persons.  
     This allows for the framework ( 1 ) to be closed with a timber board at the bottom that provides an air chamber ( 5 ) between the closed bottom ( 4 ) and the mattress.

BACKGROUND OF THE INVENTION

The former technique refers to a metal grill fixed to a framework also metallic used to hold the mattress.

Nowadays a small-boards grill yielding with the weight is used fixed to a framework usually made of iron. Iron bars are used just underneath the timber grill to give it firmness.

Lately sinthetic materials are used but always keeping the same structure, whose aim is to hold the mattress.

A Day bed has not small-board grill, its framework is usually covered with cloth and its base is usually near the floor. Recently an iron framework covered with cloth, in the shape of a box to hold the mattress is being used.

BRIEF SUMMARY OF THE INVENTION

Complete compact structure composed of a external wooden framework (1) assembled to corner pieces (6) and a closed bottom (4) in the shape of a rectangular box. Its inside consists of a horizontal small-board grill (2) resting upon wooden crossbars (3) which are linked to both opposite sides of the framework. The inside cavity between the bottom and the small-board grill provides an air chamber (5) when it receives the mattress.

Because of the air chamber it provides isolation. Because of the inner wooden crossbars it provides firmness for the mattress without making use of iron, with the iron bars.

Opposite pieces of the framework are alike. Corner pieces are all the same as well as the wooden crossbars and the small-boards too, that gives a whole uniform set.

The object of the invention is to supply for the human been a more convenient set to rest and sleep commensurate with wooden industry.

DETAILED DESCRIPTION OF THE INVENTION

The Drawer-sommier is something more than mere support for the mattress. It has evolved from a plane form without volume (like a metal box sommier or a combination of small boards and an iron framework) to another form with volume in the shape of a drawer, in which it appears an inside cavity with a closed bottom (4) and some elongated stabilizing wooden crossbars (3) which subdivide the cavity into two or more air chambers (5) according to the width required. In case of need some small holes made at the bottom of the cavity ensure the transpiration of the body.

The assembly of the several parts which compose the Drawer-sommier is made according to the technique used for carpentry industry.

The variability of the several measurements for its manufacture is a characteristic of the Drawer-sommier according to the demand of the market. These can be so small that they can be adapted to a cradle.

Diversity of the Invention:

-   a) Rectangular shape to be fixed to a front and back. -   b) Rounded corners at an extreme side to be used with legs or     others. -   1. Mattress on the surface.     -   1.1 Independent small-board grill.     -   1.2 Fixed small-board grill. -   2. Embedded mattress.     -   2.1 Idependent small-board grill.     -   2.2 Fixed small-board grill.     -   2.3 Independent small boards embedded in framework.

The rigidity of the whole supplies a straight position without curves to the human body when resting due to the stabilizing wooden crossbars which keep the small-boards grill (2) firm. Iron is conductor of electricity, electromagnetic and sound waves as well as a thermal conductor and it would go against the principal characteristic of the invention, which is isolation. On the contrary, wood in its natural state is isolating.

The own versatility of the Drawer-sommier somehow allows its personalization, since the user can, if apropriate for resting or health, to replace some of the independent small-boards with other thicker ones added (7) in order to raise some part of his body and, thus, achieve the best position.

No fabric covering the Drawer-sommier is necessary when it is commercially presented because it is already aesthetic.

No purchassing of a box sommier is necessary to complete the bed.

The confort added to the body by its air chamber makes the purchase of a special mattress unnecessary, thus reducing the cost of the whole set.

The wooden framework (1) is the essencial part of its structure and aesthetics. Its assembly will be made by fitting the parts of the framework together and the corner pieces (6) will be inlayed and glued in place; this cannot be dismantled. However, they can also be put together with a reinforcement corner in wood or metal; then it can be dismantled.

The wooden crossbars (3) hold the weight and are assembled to the framework and fixed to it by an inside reinforcement angle of wood or metal.

The small-board grill (2) is made of independent small boards (9) which rest upon the wooden crossbars (3) Their length and their small thickness allows for these to be made rounded slightly upwards, being introduced in side holes. These are fixed downwards forming the firm support of the mattress. The bottom (4) is made of timber board and it is fixed to the framework by a rebatting, glued and/or screwed, which would reinforce the solidity of the whole.

The drawer-sommier can be manufactured in mass production in a standard way due to its all-uniform pieces, which aims at a normalized fabrication (just like metallic sommiers are made at independent factories).

It would become an essencial tool for the industrial carpentry manufacturers or the craftsmen, regarding bed making, it would minimizes a lot of work and time, reducing costs (see the Diversity of the invention and Exemple of industrial usage, fig. no. 9). It can be fitted to bed-backs with an anchorage dispositive (8), its aproximation is carryed out without external perception. 

1. The Drawer-sommier whose outline consists of a rectangular wooden framework (1) in the shape of a drawer and a small-board grill (2) used to support the mattress. The mattress can lie on the framework or be slightly embedded according to the diversity of the invention It is characterized: by the incorporation of inner wooden crossbars (3) linked to both opposite sides of the framework, their height starts at the bottom and ends at the small-boards grill giving it support and firmness Also, by incorporating a closed bottom (4) of timber board which is jointed to the crossbars and the framework by its lower part; this produces an air chamber (5) between the closed bottom and the mattress By the incorporation, besides, of corner inlayed pieces (6) which are assembled in the framework By the incorporation, moreover, of independent added small boards (7) (thicker than the normal ones and tooth form shaped to keep the flexibility) in order to replace them if necessary And by the incorporation, furthermore, of an anchorage dispositive (8) composed of two screws welded to an iron plate in order to fix a bed-back to the Drawer-sommier.
